目的

探讨外周血T淋巴细胞亚群在新型冠状病毒肺炎(COVID-19)患者中的变化及意义。

方法

回顾性分析2020年1月23日至3月10日武汉大学人民医院收治的507例COVID-19患者外周血淋巴细胞亚群变化。其中,普通型249例,重型217例及危重型41例。

结果

507例COVID-19患者中,普通型、重型及危重型患者外周血CD3+、CD4+、CD8+ T细胞数均存在差异,随着疾病程度加重,均呈下降趋势;与普通型相比,重型、危重型的CD3+、CD4+、CD8+ T细胞数显著降低,差异有统计学意义(P均<0.05),且危重型患者上述T淋巴细数目较重型下降更显著,差异有统计学意义(P<0.05);此外,341例COVID-19患者中,死亡病例组CD3+、CD4+、CD8+ T淋巴细胞数目较治愈组显著降低,差异有统计学意义(P均<0.01)。

结论

重型、危重型COVID-19患者细胞免疫功能损伤更显著,外周血T淋巴细胞亚群变化与COVID-19疾病分型及预后显著相关,有助于评估疾病严重程度及判断预后。

Objective

To investigate the clinical significance of changes of peripheral blood T lymphocyte subsets in patients with coronavirus disease 2019 (COVID-19).

Methods

The changes of lymphocyte subsets in peripheral blood of 507 patients with COVID-19 who were admitted to People's Hospital of Wuhan University on January 23, 2020 and March 10, 2020 were retrospectively analyzed. Among them, 249 cases had common-type COVID-19, 217 had severe-type, and 41 had critical-type.

Results

There were significant differences in the numbers of CD3+, CD4+, and CD8+ T cells in the peripheral blood among patients with common-type, severe-type, and critical-type COVID-19, and all showed a decreasing trend with the aggravation of disease degree. Compared with the common-type, the numbers of CD3+, CD4+, and CD8+ T cells in the severe- and critical-types were significantly decreased (P<0.05), and the numbers of the above T lymphocyte subsets in the critical-type were significantly lower than those in the severe-type (P<0.05). In addition, in 341 patients with COVID-19, the numbers of CD3+, CD4+, and CD8+ T lymphocytes in the death group was significantly lower than that in the cured group (P<0.01).

Conclusion

Cellular immune function impairment is more significant in patients with severe and critical COVID-19, and the changes of T lymphocyte subsets in peripheral blood are significantly correlated with the classification and prognosis of COVID-19, which is helpful to evaluate the severity of the disease and predict the prognosis.
